What is the Exact HS Code for Cadmium Sulfide in 2025?
The primary HS code for cadmium sulfide remains 2830.30 under the 2025 Harmonized System nomenclature.
This 6-digit code applies globally:
- 28: Inorganic chemicals; organic or inorganic compounds of precious metals
- 30: Metal sulfides; polysulfides
- .30: Specifically cadmium sulfide (CdS)
Countries may extend to 8-10 digits for national tariffs. Verify with local customs.
Cadmium Sulfide Properties and Industrial Applications
Cadmium sulfide (CdS) is a yellow crystalline compound with semiconductor properties, vital in multiple sectors.
- Pigments for ceramics, plastics, and paints
- Phosphors in LEDs and displays
- Window layers in thin-film solar cells
- Photoresistors and optical sensors
- Quantum dots for advanced electronics
In 2025, demand grows in renewables despite toxicity concerns.
How to Classify Cadmium Sulfide Under HS 2830.30 Correctly
Accurate HS code classification prevents delays and penalties.
- Confirm purity and form (powder, crystals)
- Exclude mixtures; pure CdS = 2830.30
- Check if it's synthetic or natural
- Review exclusions like cadmium pigments (3206)
- Consult WCO HS Explanatory Notes
Use official databases for 2025 updates—no major WCO changes until 2027.
